Billie Eilish Live in NYC

Billie Eilish is having quite a busy 2018 so far. The LA-native is traveling North America on her sold out Where's My Mind tour with opening act Reo Cragun, she just performed "Bellyache" on The Tonight Show With Jimmy Fallon and she joined a March for Our Lives protest in Boston. Her coordinated outfits, often including oversized jackets and designer pieces, are making her quite the style icon, inspiring the audience to come dressed like her.

Eilish opened her set on Friday night (March 23) -- the first of two sold out shows at New York's Bowery Ballroom -- with "Bellyache." Fans were screaming with excitement, singing along to every word. Her voice is incredible and her lyrics are personal, which is why fans relate so well -- they see themselves living through the same situations. During the set, she thanked the audience for being the reason she's alive and standing on the stage to perform. 

At just sixteen years old, there are no signs of her slowing down anytime soon. She's about to take over. Check out some of the photos from the show below.
